K. TSCHAEPE WINDOW GUARD Filed April l0, 1939 3 Sheets-Sheet 3 InventorAttorneys v Patented July 30, 1940 UNITED l'STATES PATENT OFFICE j2,209,742l Y v l i WINDOW GUARD Kurt Tschaepe, New York, N. ApplicationApril 1o, 1939, serial No. 267.084 2 claims. (o1. 2o-71)j Thisinventionrelates to a window guard for preventing persons from fallingfrom the window, 'the general object ofl the invention being to providea guard which is adjusted to be fas- 5 tened vto the inside of `avwindow frame or wall,

said guard being so formed thatit can be moved from the inside of awindow to the outside thereof and ,moved back to theposition inside of awindow without the operator moving outside of the ,-;window. When vtheguard islocated at the inside of the lwindow it will prevent personsfrom falling through the window and when located outside of the Windowit will prevent window cleaners and other persons working outside of x.;the window from falling therefrom.

, Another object of the ,invention is to provide latch meansforholdingrtherparts in adjusted positon.,.

This invention also consistsr in certain other 2gAV features ofconstruction and in the combination and arrangement of the several partsto be hereinafter'fully described, illustrated in the accompanyingdrawings and specifically pointed out in the appended claims.

In describing theinvention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the 'several views, and in which:

Figure 1 is a fragmentary view looking toward I a window and showing theinvention inuse therein with the device in position extending across thelower part of the Awindow opening.

Figure 2 is a similar view but showing the device in position extendingfrom the outer part of the window.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a section on the .line 4-4 of Figure 2.

Figure 5 is a section on the line 5-5 of Figure 1.

Figure 6 is a fragmentary longitudinal secbers of a window frame bybolts 2 and a lug 3 extends outwardly from thecentral part of each barinto the window opening. Each lug has an annular groove 4 -therein intowhich extends a beveled projection 5` which is formed kby terminat-A ingthe ends of the groove in spaced relation.

A pair of arms 6 each has a cylinder 'I attached to oneend and thesecylinders fit vover the lugs 3 and each cylinder has an internalprojection 8 fitting in the groove 4.*Thus the arms 6 are pivotallysupported. on the lugs 3 andl these projections Sand A8 permit the armsto be swung in an arc of 270 degrees.

The other ends vof the arms v6 arevconnectedto asecond pair of arms 9 bythe bolts I0 and nuts: II, the 'two` bolts being placed in a spacer II`which extends,betweenthearms 9 and the bolts I Il arefastened in thespacer by the rivets I2. The twoarms 9y are connected together by thecross members|3 Whichmay also be elongatedA bolts passing'throughspacers. The outer end of each arm 6 is of substantially circular shapeas shown at I4 but provided with the stop shoulders I5 and theadjacentend of each arm 9 is forrnedv with an arcuate: flange I6 whichslidesover the arcuate part I4 butis limited in its movement by thestopshoulders I5. These parts are vso arranged as tofpermit each arm 9to be moved.l from a position overlying an arm 6 to a position.wherethearm9 extends at-right angles to the The projections 5 Iand `8are so arrangedasl to permit the arms 6 to extend vertically downwardlyat the inner part of the window opening as shown in Figure 1 and then tobe moved upwardly and outwardly to a position where the arms 6 extendhorizontally through the window opening as shown in Figure 3. When theguard is in position extending across the lower portion of the windowopening as shown in Figure 1 the frame composed of the parts 9 and I3extends substantially parallel with the arms 6 as shown in Figure 1 soas to prevent anyone falling through the window and in this position ofthe parts the arms 6 cannot move outwardly through the window openingdue to the stops 5 and 8 being in engagement. When the arms 6 are movedupwardly and outwardly to the position shown in Figure 3 the arms 9 andthe cross bars I3 are swung downwardly and outwardly to the positionshown in Figure 3 and when the parts reach this position, the arms 6 arelocked in the horizontal position shown in Figure 3 by means of latchpins I'I projected by springs through holes I8 in the cylinders I andinto holes I9 in 55 the lugs 3 when said arms 6 are moved to thehorizontal position as shown in Figure 3. Each pin I1 is carried by across piece 20 having the rods 2l attached thereto which pass throughholes in the stationary cross piece 22 on each arm 6 and the springs 23act to project the pin I1 into the holes I8 and I9. The cross piece 20is beveled as at 29 and when each arm 9 is swung to a position over anarm 6 an angle lug 25 on said arm 9 will engage the bevel 20 and thusforce the latch pin 1 outrof the holes so as to reiease the arms 6 topermit them to be swung on the pivots. When an arm 9 is in overlappingposition on an arm 6 a latch pin 21 on a spring plate 28 carried by anarm 6 engages a hole 29 in an arm 9 to lock; the two sets of armstogether in overlapping relation in the position they occupy in Figure 1and'also in Figure 6. Each pin 21 can be pushed from its hole 29 bypressing an object into the hole 29 against the pin 21.

In addition to the bolts 2 for fastening the plates I to the sidemembers of the Window frame, pins 2 may be used for connecting thesupporting members to the window sill by making said members ofconsiderable length as shown in Figure 10. at I.

From the foregoing it will be seen that the window guard can be readilymoved to the position shown in Figure 1 where it will extend across thelower part of the window opening and the parts are held against outwardmovement so that the guard will prevent anyone-from falling out of thewindow. Then when a window cleaner is cleaning the windows or the windowis to be worked upon from the outside, then the arms 6 are swungupwardly and outwardly, carrying the arms 9 with them until arms 6 reachthe horizontal position shown in Figure 3. Then the arms 9 are swungdownwardly and outwardly and as the arms 9 leave the arms 6 the members25 will leave the members 20 so that the springs can project the latchpins I1 into locking position to lock the arms 6 in horizontal position.When the arms 9 reach a vertical position as shown in Figure 3 an end ofeach flange I6 will engage the stop I5 which will prevent the Inembers 9from swinging outwardly beyond the-vertical position.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.

Having described the claimed as new is:

1. A window guard of the class described comprising supporting membersattached to the side members of a window frame, a pair of arms havingone end pivotally connected with the supporting members, stop means forlimiting swinging movement of the arms to three-quarters of a circle andfrom a depending vertical position upwardly and inwardly and thenoutwardly to a horizontal position where the arms extend outwardlythrough the window opening, a frame including arms pivoted to the freeends of the rst-mentioned arms, stop means for limiting movement of theframe on the first-mentioned arms beyond a Vertical position when thefirstmentioned arms are in outward horizontal position, and springactuated latch means for locking the rst-mentioned arms in saidhorizontal position extending outwardly from the window as saidnrst-mentioned arms reach said horizontal position.-

2. A window guard of the class described comprising supporting membersattached to the side members of a window frame, pivot lugs extendingoutwardly from said supporting members, a pair of arms, cylindersconnected with the arms adjacent one end thereof and rotatably arrangedon the lugs, means for limiting swinging movement of the arms on thelugs to permit the arms to be placed in a vertical position extendingdownwardly or in a horizontal position extending outwardly, a frameincluding arms pivoted to the free ends of the rst-mentioned arms, stopmeans for limiting movement of the frame on the first-mentioned armsbeyond a vertical position when the first-mentioned arms are inhorizontal position, latch means for locking the firstmentioned arms inhorizontal position extending outwardly from the window, and means forautomatically releasing the latch means when the frame is swung intoparallel position with the rst-mentioned arms and latch means forholding the arms of the frame in parallel position with thefirst-mentioned arms.
